calibrating touch screen

svicar

I have very poor response on touch screen. Sometimes the "click" is not working. I must put more presure to work. You can see this when typing or when you make two finger zoom on the pictures. Also double click to wake up the display when locked is not working every time.
I think that the touch must be calibrated.
Does somebody know how to do this?
thank you.

Capacitive touch screens cannot be calibrated. You can just forget that about all smart phones of the current days. Remove the stock screen protector. That's not made for use. If your skin on hand is dry, that can reduce the efficiency of the touchscreen but a capacitive touchscreen has no sensors to perceive pressure.

i have problems with the screen with a tempered glass and without glass. i that is a problem of software or hardware. Umi must clarify the matter. i am very upset with this phone. Bad software, no led, fails with touchscreen... what's more umi emax mini???

I have the same issue like you svicar.
I have the tempered glass from UMI applied on the screen.
I've ordered another tempered glass to see if I will notice improvements.
I will write here the news.

Yes, there is a problem hard or software because not screen protector (why stock applied if not usable? It's not a simply film protector for packaging!) nor tempered glass are the cause. I hope solving this problem and beg your pardon for my bad english

Fortunately I've got an emax mini in possession, so I know what I'm talking about. The factory installed screen protector is made of soft plastic and meant to protect the screen in transport. I found that, the capacitive range of this model is very short, so an additional layer on the screen can seriously reduce its efficiency. That might be possible by a software update to increase the electromagnetic tension of the touch panel to make it able to work properly with screen protectors, but a such adjustment can reduce the accuracy of the touch screen as well. Without screen protector (I never use them and even no scratches at all) this phone works perfectly at me.

What about tepered glass that is sold as UMI official/original for eMax Mini:

Is it suitable or it also causes troubles to touch?

At least they're made for usage but I don't recommend them.
